Description
Example:
poller-wrapper.py -exclude 10.1.0.0/24, 10.1.1.4/29
This would make it possible for multiple pollers to be used in environments where each data center will have its own poller but share the same shared mysql server/rrdtool store.

We would only accept such a feature if it was well thought out and useful to more than one person. It's structural suicide to accept every random idea.
You don't seem to have added the ability to exclude a location, which would seem to be important.
In any event. I think it's more useful to be able to do this sort of thing in the Web UI. We've previously discussed ways of doing this, but we've not really had any instances where it's been necessary.
In general one should think very carefully about having remote pollers, since SNMP is designed to travel long distances, but MySQL and storage protocols are not.
You shouldn't be using IPs in Observium. Thus this whole concept makes little sense.
A simple patch to make the wrapper poll devices based on the locations, already listed in the database.[^patch.diff]. Rusty coder alert, definitely needs review.
Just a thought, since location info is already stored in the device table, could it be used to limit polled devices instead since using CIDR as that would need additional IP resolution.
For example
poller-wrapper.py -locaton dc1
poller-wrapper.py -location dc3 dc4
I believe the functionality to filter devices to be polled is already present based on host names and the reason in code explains it well.
poller-wrapper.py
"Additionally, if a hostname wildcard is passed, add it to the where clause. This is
important in cases where you have pollers distributed geographically and want to limit
pollers to polling hosts matching their geographic naming scheme."
It would be nice to extend this feature to based on CIDRs as this is normally how the network is segmented.
For example, a poller servicing a location with the 10.1.0.0/16 subnet and another servicing the 10.2.0.0/16 subnet.
Which sense would it have? I don't see any advantage with this feature.
This is amazing! I really needed this feature. Now I can poll by location, os, and even syscontact. Thanks a lot!
